💸 Tips for Saving Money on Bathroom Renovation

Renovating a bathroom doesn’t have to drain your wallet. Here are cost-effective strategies:

  1. Keep Plumbing in the Same Position

Relocating plumbing fixtures is one of the most expensive aspects of a bathroom remodel. Keeping your toilet, shower, and sink in the same location can save up to £1,000–£2,000.

  1. Use Imitation Materials

Porcelain tiles that mimic marble or laminate counters that resemble granite can cut material costs by over 40%, while still offering visual appeal.

  1. Buy from Discount or Trade Suppliers

Affordable bathroom fittings can be sourced from:

Victoria Plum

Wickes TradePro

B&Q Clearance

Screwfix

Online marketplaces like eBay or FB Marketplace

Many suppliers also offer delivery or bundle discounts.

  1. Mix High and Low-End Fixtures

Splurge on the focal point—such as a stylish vanity or rainfall shower—and save on basic items like taps or mirror cabinets. This strategy maintains quality without overspending.

  1. Opt for Partial Renovations

If your layout and plumbing are sound, consider updating only certain parts:

Regrouting tiles

Installing a new toilet or basin

Replacing the shower screen

These updates can cost as little as £500–£1,500.


🧰 DIY vs Professional Installation

Doing it yourself can save up to 30–40% in labour costs, especially for tasks like painting, tiling, or fixture assembly. However, plumbing and waterproofing should be left to professionals to avoid costly mistakes.
